No I haven't personally however I have received feedback from people I trust. It's great! It should be understood that ARC listens to the tubes for a long time as well as life tests the tubes before they give their ok. If the tube sounded bad, they wouldn't be using it in their products. Your going to get a bit more slam and impact with the KT-120 and not in a bad way. It has an effortless quality. Very musical. The funny thing is I remember my old Dyna MK III's with the tung sol 6550 Coke Bottle tubes in them, and they were awesome. More slam, more impact w/o sacrificing any detail. By more slam I mean better transient impact. I think it's going to be a win win but only time will tell. G
Audio Research VS 115 bias Adjustments
Any A-goners familiar with setting bias on the ARC VS115 power amp??
Just checked and set the bias on my VS115 amp. For those who are familiar with the process on this amp, I checked and adjusted the 4 "Set" ports to 65mV, as specified. However, the bias readings from the other 4 "Check" ports ranges from 63-71mV. While technically in "spec" (i.e., 57-73mV for the "Check" ports), I would have thought the range of bias readings from the "Check" ports would not have been that much. As you know, the bias voltage for the "Check" power tubes cannot be adjusted.
As an aside, I only use ARC matched tubes.
Does anyone know whether the range of bias mV readings on the "Check" tubes is normal (whatever that means) or otherwise could result in a denigration of sound??
